Punching Elasticity Adjustment Structure

ABSTRACT

The present invention relates to a punching elasticity adjustment structure which comprises one punching bag connecting set, one elastic bladder, one air valve, one base, and one elastomer. The said elastic bladder is inflated via said air valve to increase the inner pressure so the said elastic bladder expands vertically with rised height, resulting in bigger gap between said punching hag connecting set and said base and simultaneously elongates said elastomer and changes its elasticity. Elasticity therefore can be adjusted to meet the demand of diversified training effects.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a punching elasticity adjustment structure; particularly one that using elastomer driven by degree of air bladder inflation to adjust punching training devices.

2. Description of Prior Arts

Principle of conventional martial training device is: one punching bag (such as speed bag or filler bag), when punched by external force, will swing back and forth or absorb the impact utilizing elasticity of elastomer connecting to said punching bag.

Elastic coefficients of elastomer of most said martial training devices are fixed so elastic strength and flexibility cannot be adjusted upon different needs, resulting in insufficient combat training. There are a small number of existing training devices which are elasticity-adjustable. However, they are either done by rigid structures adjusted by stretching spiral sleeves or screws, which may result in dangers when there is breakage due to excess impact or users may be injured by direct hit on the structure; or it may be done by mere air inflation of elastic bladder, resulting in insufficient elasticity to meet demanded strength for training.

Thus, there are foregoing drawbacks of conventional elastic structure of punching training device in prior art to be improved.
